Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of non-woven product processing device, and particularly relates to a glue spraying device for glue spraying cotton production. BACKGROUND

[0002] The aforementioned glue spraying cotton, also known as sprayed pulp cotton, is a kind of non-woven product, i.e. non-woven cloth. The forming mechanism of the glue spraying cotton is that the adhesive as glue is sprayed on the surface of the fluffy fiber layer carried by the guide cotton curtain and in a running state, and then the fiber layer is dried and solidified so that the intersection points between the fibers are bonded, and the fibers that are not bonded with each other still have a large degree of freedom. At the same time, in the three-dimensional network structure, many air-containing gaps are still retained. Due to the porous nature, good air permeability, dry and wet washing resistance, and high loft warmth retention of the fiber layer of the glue spraying cotton, the glue spraying cotton is widely used for making ski jackets, space suits, cotton quilts, sleeping bags, and hygiene protection products such as mask materials, pads, and the like.

[0003] According to the industry, in the complete set of production equipment of spraying glue cotton, the glue spraying device is an indispensable important equipment, and can be found in the disclosed Chinese patent documents, such as CN213669951U recommended "a glue spraying machine with good glue spraying effect", CN214937995U provides "a glue spraying device for glue cotton production", CN115538038B introduces "a glue spraying device for glue cotton production", and CN108754869B proposes "a reciprocating glue spraying device for glue cotton production", etc. The foregoing patents are not limited to the above, although each has the technical effect described in the specification, but there are the following common disadvantages: because the width (also known as "width") of the glue spraying cotton is not the same, for example, 1.5m, 1.8m, 2m, 2.2m, etc., therefore the reciprocating stroke of the glue spraying head or glue spraying nozzle also needs to be adapted to the above width. For example, in the state of processing the first batch of products with 2m wide glue spraying cotton, and processing the next batch of products with 1.5m or 1.8m width, if the reciprocating stroke of the glue spraying head is not changed to adapt to the width of 1.5m or 1.8m, there is no doubt that it will be difficult to adapt or cause waste of glue. The current solution usually has the following two kinds: one is to provide as much as possible glue spraying device suitable for the width of glue spraying cotton; the second is to use program control to drive the forward and reverse rotation of the motor to drive the glue spraying head (i.e. glue spraying nozzle) to adapt to the width (i.e. width) of the glue spraying cotton required. The first method of the above two methods not only increases the equipment investment cost of the manufacturer producing glue spraying cotton products, but also causes large space occupation, high idle rate of equipment (because the probability of simultaneously processing different specifications of glue spraying cotton is relatively low under normal circumstances), and large equipment maintenance workload; the second method of the above two methods can make a device adapt to the glue spraying of different specifications of glue spraying cotton, but the cost of electrical control system and motor such as servo motor is relatively high, and the maintenance and repair cost is also large. Especially, the adjustment operation of the electrical controller needs the participation of technical personnel, which is often difficult for ordinary workers working online, and the adjustment operation of the electrical control must also pay attention to safety. In addition, due to the difficulty of intuitive adjustment, it is impossible to intervene and correct the deviation (correct) in time. SUMMARY

The front and rear ends of the lower roller 58 form a rolling pair with the front and rear surfaces of the middle guide rib 34 of the lower roller on the guide beam, respectively. The cross-sectional shape of the guide beam 3 is I-shaped. This structural design ensures that the upper left and right rollers 54 and 56 and the lower roller 58 will not move back and forth during movement, ensuring an optimal rolling pair effect with the guide beam 3.

[0033] Please refer to Figure 3 And in combination Figure 1 The aforementioned signal detection rod driving mechanism 6 includes a driving gear 61, a driven gear 62, a gear transmission chain 63, and a detection rod front and rear displacement screw 64, the driving gear 61 is fixed at the front end of the aforementioned reciprocating transmission belt pulley driven shaft 45, the front end of the detection rod front and rear displacement screw 64 is rotatably supported on the screw front support bearing seat 641 and extends to the front side of the screw front support bearing seat 641, while the rear end of the detection rod front and rear displacement screw 64 is rotatably supported on the screw rear support bearing seat 642, and the screw front and rear support bearing seats 641, 642 are fixed on the bearing seat bracket 65, and the bearing seat bracket 65 is fixed on the left side of the aforementioned [character shape extension frame 14, the driven gear 62 is fixed at the front end of the detection rod front and rear displacement screw 64, one end of the gear transmission chain 63 is sleeved on the driving gear 61, and the other end is sleeved on the driven gear 62, the right end of the aforementioned glue spraying cotton width detection rod 7 is fixed with the detection rod sliding block 71, and the detection rod sliding block 71 is threadedly connected with the detection rod front and rear displacement screw 64; The aforementioned glue spraying cotton width detection rod position signal acquisition mechanism 8 is arranged on the left side of the aforementioned bearing seat bracket 65 corresponding to the position of the left end of the aforementioned glue spraying cotton width detection rod 7.

[0034] The aforementioned glue spraying cotton width detection rod position signal acquisition mechanism 8 includes an adjusting slide rod fixed plate 81, an adjusting slide rod 82, a front position signal collector 83, and a rear position signal collector 84, the adjusting slide rod fixed plate 81 is fixed on the left side of the aforementioned bearing seat bracket 65, a detection rod moving accommodation groove 811 is formed on the upper part of the length direction of the adjusting slide rod fixed plate 81, the left end of the aforementioned glue spraying cotton width detection rod 7 passes through the detection rod moving accommodation groove 811 to extend to the area corresponding to the aforementioned front position signal collector 83 and rear position signal collector 84 in a horizontal cantilever state, the adjusting slide rod 82 is shaped like a Chinese character “ㄇ” and is fixed on the left side of the adjusting slide rod fixed plate 81 corresponding to the position below the detection rod moving accommodation groove 811, the front position signal collector 83 and the rear position signal collector 84 are movably arranged on the adjusting slide rod 82 in a front and rear corresponding state, that is, they can be adjusted as needed, and the front position signal collector 83 and the rear position signal collector 84 are electrically connected with the electrical controller in the use state. Figure 1 And Figure 3As shown, the aforementioned front position signal collector 83 is fixed on a front position signal collector fixing seat 831, and a front position signal collector fixing seat sliding block 8311 is fixed on the right side of the front position signal collector fixing seat 831, which is in sliding fit with the front end of the adjusting slide rod 82; similarly, the aforementioned rear position signal collector 84 is fixed on a rear position signal collector fixing seat 841, and a rear position signal collector fixing seat sliding block 8411 is fixed on the right side of the rear position signal collector fixing seat 841, which is in sliding fit with the rear end of the adjusting slide rod 82. From the foregoing description, it can be determined without doubt that the glue spraying cotton width detection rod 7 alternately corresponds to the front position signal collector 83 and the rear position signal collector 84.

[0035] In the present embodiment, the aforementioned front position signal collector 83 and the rear position signal collector 84 are position proximity switches, but travel switches, micro switches, reed tubes or Hall inductive elements can also be used.

[0036] Continuing to see Figure 1 and Figure 3 When the aforementioned reciprocating transmission driven pulley 46 drives the aforementioned reciprocating transmission pulley driven shaft 45 to move (alternating forward and reverse rotation), the structure system of the signal detection rod driving mechanism 6 is driven by the driving gear 61, which is driven by the reciprocating transmission pulley driven shaft 45, through the gear transmission chain 63 to drive the driven gear 62, which is driven by the detection rod forward and backward displacement screw 64, which is driven by the forward and backward rotation of the detection rod forward and backward displacement screw 64 to drive the detection rod sliding block 71 to move forward or backward correspondingly, which is driven by the detection rod sliding block 71 to drive the glue spraying cotton width detection rod 7, when the glue spraying cotton width detection rod 7 corresponds to the front position signal collector 83, the signal is collected by the front position signal collector 83 and fed back to the electrical controller, and the signal is given to the driving motor 41 by the electrical controller, so that the driving motor 41 moves in the opposite direction of the previous movement, and when the glue spraying cotton width detection rod 7 corresponds to the rear position signal collector 84, the signal is collected by the rear position signal collector 84 and fed back to the electrical controller, and the signal is given to the driving motor 41 by the electrical controller, so that the driving motor 41 moves in the opposite direction of the previous movement. Therefore, assuming that the working speed of the driving motor 41 remains unchanged, the left and right alternating displacement of a group of glue spraying nozzles 59 is realized by the alternating change of forward and reverse rotation of the driving motor 41.

[0037] As can be seen from the above description, when the distance between the front and rear position signal collectors 83, 84 is large, the one-way stroke (left and right) of the group of glue spraying nozzles 59 is also large, and the width of the glue spraying cotton that can be adapted, i.e. the width of the door, is also large. However, when the glue spraying cotton of a smaller width than the previous one is replaced, as long as the positions of the front and rear position signal collectors 83, 84 are moved closer to each other by the online operator, the reciprocating speed of the group of glue spraying nozzles 59 is increased (i.e. the reciprocating time is shortened), that is, the forward and reverse rotation speed of the driving motor 41 is accelerated, and vice versa.

[0038] In summary, the technical solution provided by the present application remedies the shortcomings in the prior art, successfully completes the invention task, and faithfully realizes the technical effects described by the applicant in the technical effect column above.
